Moved
Moved from Tesarius.

Based on Rakovic (1984): pronotum with three-plus rows of punctures; color dark brown; elytral margins lacking setae.

Moved
Moved from Psammodiini.

Can key to genus for now; will try species later tonight if Phil or someone does not get to it first.

 
i alerted Paul Skelley; not sure he's around, though

Moved
Moved from Aegialia.

This is a psammodine; can key it out later tonight if someone does not get to it first.

 
thanks, Blaine -- i was about to correct my error; Tesarius?

 
Yes
I do believe so; the shape, size, pronotal structure and reduced eyes are supportive. There are four spp. in CA so not sure of the species, yet. All my literature is at home.

 
great
we got some new pictures - that nails it. New genus for the guide!

Moved
Moved from ID Request.

Are the
tips [barely] of the mandibles exposed? Compare. If not, this might be Tesarius - similar to the generally eastern Geopsammodius, already in the guide. Good find. More shots would be helpful - especially the head and pronotum. Tesarius also have reduced eyes. Additionally, I think I see typical Psammodiine tarsomeres - could be wrong on that though.

this could be very interesting...
please post more shots if possible, and preferably brighter, sharper images. This could be an aegialiine scarab!

 
Blaine, some time we
need to talk about Aegialia in GA!

 
hey Phil
sometime we need to talk about SE scarabs (and other beetles) in general :-) Feel free to contact me by email or FB anytime!
